Winter weather conditions play a significant role in the operation of the surface transportation system. When water freezes on the road surface or blowing snow obscures visibility, motorist safety may be compromised. Moreover, the presence of snow or ice on the roadway can reduce travel speeds until appropriate winter maintenance activities are undertaken. These effects are often thought of in causative ways: for example, an increase in bad winter weather conditions will result in an increase in crashes and an increase in winter maintenance costs. If these causative relationships could be quantified, this could have far-reaching impacts, including facilitating proactive approaches to winter roadway safety, assessing the cost- effectiveness of various winter maintenance resources, evaluating the effectiveness of safety projects while taking into account the impacts of unusal weather, and others.
